Title: Seal ring for tube joints - with semicircular part of hard and sectorial part of soft elastomer
Inventor: STROEM TORSTEN ERIK THEODOR
IPC: F16L21/03
Filed: 1979-03-14
Abstract: A seal ring for a joint between two tube ends is accommodated in a semicircular inner groove of the socket end of a tube and seals against the spigot at the other end. The seal ring consists of a major part of semicircular cross-section which is made of a harder elastomer (at least 80 Shore) and has a smooth outer surface in engagement with the groove. It is made in one piece with a sector-shaped elastomer part at one half of its dia. which consists of a softer elastomer (40 or 50 Shore). Before the joint is made, the soft part is flush with the tube wall and the harder part protrudes. Insertion of the spigot end causes it to turn so that the soft part produces a good seal. Such a seal does not become damaged by the insertion of the spigot end and ensures a reliable sealing action.

Title: Audible signal emitter for electric waffle iron - has bimetal switch in circuit parallel to main thermal switch for initiating alarm
Inventor: CLOER GUENTHER
IPC: G05D23/275
Filed: 1979-10-04
Abstract: The circuit (10) for the waffle iron warning system is connected in parallel with the mainswitch (13) which turns on the hot plates (11,12) and consists of a signal transmitter (15) controlled by a bimetallic contact (16) with a heating element (17). When the main thermal switch (13) is closed, no current flows in the parallel circuit (20) although the bimetallic switch (16) is made. When the supply switch is closed to feed the operating voltage to the waffle iron, the thermal switch (13) is in the shut position, but as soon as the set temperature is reached, this switch opens allowing current to flow in the parallel circuit (20). The signal transmitter emits an acoustic signal but since the bimetal heating coil (17) is also parallel to the signal device, (15), it heats up and shuts it off after a pre-determined time.

Title: Incoming unipolar binary recognition circuit - compares standing DC of received signal with expected median for circuit characteristics to verify receipt of ones or zeros
Inventor: SCHULZE RAINER
IPC: H04L25/06
Filed: 1980-01-30
Abstract: The method of recognising unipolar binary on an incoming transmission circuit is by correlating the expected binary signal with the amplitude of the received signal. The characteristics of the transmission channel are known and are equated to the bit rate to determinea median amplitude level. The incoming signal on the channel (1) is divided between a delay free amplifier (6) and a delay line path (8) both paths are combined at an adder (7) before being input to a comparator (9) with specified hysterisis. The design is for higher transmission speeds and is to overcome the distorting effects of line capacitance, inductance etc. over longer transmission lengths. The rise and fall of the incoming signal standing d.c.is therefore compared with the expected median level to determine that ones, when still rising, or Zeros, when falling below median are incoming.
